The seller, Wheel Fanatyk, on Ebay also says that wood rims needn't be coddled. He is based in the Northwest and has ridden his in the rain without trouble. I have several hundred miles on both sets of wheels that I built with his Ghilaso rims and no problems. One set of rims even got wet in a rain shower, I wiped them down when I got home and they're fine.
